Introduction


1.3.1 The BreezeNET PRO.11 Access PointThe BreezeNET PRO.11 Access Point is fully compliant with the IEEE 802.11Wireless LAN standard.

The Access Point is a wireless hub that provides access for wireless workstationsinto wired Ethernet LANs. It also contains the wireless relaying function thatenables workstations equipped with a Station Adapter (Station Adapter, Bridge, andSA-PCR) to communicate with one another inside the cell coverage area (even ifthey are not in direct line of sight) via the Access Point. Any two wireless stationsin two different cells can communicate through their Access Points.

The BreezeNET Access Point can support various data rates simultaneously: at3 Mbps, 2 Mbps or 1 Mbps.

Figure 1-1. AP-10 PRO.11 with TwoBuilt-in Omni-Directional Antennas

Mobile workstations, such as laptops and hand-held devices, can roam betweenAccess Points that belong to the same Extended Service Set (ESS). In an ExtendedService Set, all Access Points have the same ESSID. When the access points are setup so that their coverage areas overlap, users can roam seamlessly from cell to cell.This means that there is no interruption of network connection when moving fromone coverage area to the other through the overlap area. The roaming is completelytransparent to the user and the applications. The Station Adapters decide when a

Introduction


mobile user becomes disassociated from one access point and associated withanother. This process is fully transparent, requires no user intervention and involvesno loss of data packets.

Multiple Access Points can be positioned in locations where heavy network trafficis expected; this creates a multicell and increases the aggregate throughput capacityin areas where it is needed most. The system implements a Load Balancingalgorithm to divide the stations equally between the available co-located AccessPoints.

The Access Point contains an embedded SNMP agent, enabling effectivemanagement by BreezeVIEW or any standard SNMP management station.Software upgrades can be downloaded by TFTP protocol via the wired LAN orwireless LAN.

The Access Point is available in three models:

AP-10 PRO.11 with two integrated omni-directional antennas.

AP-10D PRO.11 for use with external high-gain antenna(s).

AP-10DL PRO.11 for use in Europe with high gain antenna under the ETSIstandard.

Introduction


1.3.2 The BreezeNET PRO.11 Single Station AdapterThe BreezeNET PRO.11 Single Station Adapter is a wireless LAN station adapterthat converts any device equipped with an Ethernet interface into a wireless LANstation. The Single Station Adapter is transparent to the devices hardware,software, and network operating system. This enables plug-and-play installation.

Figure 1-2. SA-10 PRO.11 with TwoIntegrated Omni-Directional Antennas

The Single Station Adapter enables its workstation to communicate with any otherwireless station in the same cell coverage area, and to access all network resourcessuch as file servers, wired stations, printers and shared databases via the AccessPoint. Any two wireless stations in two different cells can communicate throughtheir Access Points.

Workstations that can be connected to the wireless LAN include PCs, X-Terminals,and any other device that supports Ethernet. The unit is transparent to theworkgroup devices hardware, software, and network operating system.

The Single Station Adapter contains an embedded SNMP agent that enableseffective management. Software upgrades are downloaded by TFTP via theEthernet port or via the wireless LAN and Access Point.

Introduction


Network connection is maintained while roaming between overlapping coverageareas. Transmission and reception can be continued while moving at high speedwith no data packet loss or duplication.

Figure 1-4. WB-10D PRO.11 with TwoExternal Antenna Connector Ports

The Workgroup Bridge communicates with the Access Points of the remote LANs,effectively creating an extended wireless network spanning sites situated up to 6miles apart (in Europe, this range is limited by ETSI regulations to 2.5 Km; inderegulated regions, this range can be up to 60 Km). In this way a central EthernetLAN may be connected with one or more branch office LANs.

In addition, an island consisting of a Workgroup Bridge together with an AccessPoint can work as a relay. Transmissions from the central LAN and from the remoteLAN are relayed via the island located between them. This configurationeffectively doubles the bridge range.

Workstations that can be connected to the wireless LAN include PCs, X-Terminalsand any other device that supports Ethernet. The unit is transparent to theworkgroup devices hardware, software, and network operating system.

Introduction


1.4 BreezeNET PRO.11 Functional DescriptionBreezeNET PRO.11 units add wireless functionality to existing Ethernet LANs.

1.4.1 Quick Review of EthernetStandard Ethernet LAN stations are wired to a common bus. When one of thestations sends a message, it assigns a destination address to the message and sendsthe message on the bus. All stations on the bus hear the message, but only thestation with the matching address processes the message.

1.4.2 Startup ProcedureWhen wireless units (other than the AP-10) start up, they scan the frequencies foran AP-10. If an active AP-10 is in range, the units synchronize with it. Theaddresses associated with the units are registered in the AP-10 (the registrationprocess is different for each unit type). From then on, the units can send and receivemessages to and from the wired LAN.

1.4.3 AP-10 Access Point

The AP-10 Access Point is connected to a wired Ethernet LAN, and it keeps a listof known stations on its wireless side. When an AP-10 hears a message that isdestined for a wireless station, the AP-10 forwards the message wirelessly to thestation. If the message has a destination address that the AP-10 does not recognize,the AP-10 ignores the message.

The AP-10 continuously listens for wireless messages as well. When the AP-10hears a wireless message destined for another wireless unit, it relays the messagedirectly to the wireless unit without forwarding the message to the wired LAN.When the AP-10 hears a wireless message the destination of which is not on thewireless LAN, it forwards the message to the wired LAN. Messages cannot be sentdirectly between wireless stations without an AP-10 to relay the message.

Introduction


1.4.4 SA-10 Station AdapterThe SA-10 station adapter is connected to a stations network card. When thestation sends a message, the SA-10 wirelessly forwards it to the AP-10. And whenthe AP-10 receives a message destined for the station, it wirelessly forwards themessage to the SA-10.

The first time the station sends a message, the stations address is registered in theAP-10. The AP-10 keeps only the first address for each SA-10, so the SA-10 willnot work properly if connected to more than one station.

1.4.5 SA-40 Station AdapterThe SA-40 station adapter has four connectors for up to four stations, and featuresoperation identical to that of the SA-10. As each station connected to the SA-40sends its first message, each address is registered in the AP-10. The AP-10 onlykeeps up to four addresses for each SA-40, so the SA-40 will not operate properly ifconnected to more than four stations.

1.4.6 WB-10 Wireless BridgeAs opposed to the SA-10 and SA-40 that connect directly to stations, the WB-10wireless bridge connects to a wired Ethernet LAN (hub). When a station on theWB-10s LAN sends a message that is not destined for a local station, the WB-10wirelessly forwards the message to the AP-10. When the AP-10 receives a messagedestined for a station on the WB-10s LAN, the AP-10 wirelessly forwards it to theWB-10. In this way, the WB-10 and AP-10 work together like a standard networkbridge.

The first time each station on the WB-10s LAN sends a message, the stationsaddress is registered in the WB-10 and the AP-10. The WB-10 and AP-10 can holdall the addresses necessary to support an entire LAN connected to a WB-10.

Introduction


1.4.7 SA-PCR Station AdapterThe SA-PCR station adapter is inserted into the stations PCMCIA slot and featuresidentical operation to that of the SA-10. As opposed to the SA-10 and SA-40 stationadapters that connect to the stations network card, the SA-PCR is the stationsnetwork card. The SA-10 and SA-40 can be used with stations of any operatingsystem as long as the station sends legal Ethernet messages, but the SA-PCRrequires a driver that is compatible with the stations operating system.

Basic Installation


2. BASIC INSTALLATION

This chapter describes physical installation of the BreezeNET PRO.11 series unitsdescribed in Chapter 1, with the exception of the SA-PCR card. Installation of theSA-PCR PRO.11 PC card is described in Chapter 4.

The BreezeNET PRO.11 series features plug-and-play operation, i.e., the unit startsoperating immediately after physical installation with a set of default operationparameters. A local terminal can be connected to the unit to perform system-specific parameter setting. The use of a local terminal and the configurationparameters are described in Chapter 3. In addition, all products in the PRO.11 seriescontain an SNMP agent and can be configured from a remote location via thenetwork. This is described in the Appendix.

+HDW6RXUFHV

Keep the units well away from sources of heat, such as radiators and air-conditioners.

2.3.1 Additional Considerations When Positioning the AccessPoint

When positioning the AP-10 PRO.11 and AP-10DE Access Points, take intoaccount the following additional considerations.

+HLJKW

Install the Access Point at least 1.5m above the floor, clear of any high officepartitions or tall pieces of furniture in the coverage area. The Access Point can beplaced on a high shelf, or can be attached to the ceiling or a wall using a mountingbracket.

&HQWUDO/RFDWLRQ

Install the Access Point in a central location in the intended coverage area. Goodpositions are:

In the center of a large room

In the center of a corridor

At the intersection of two corridors

Many modern buildings have partitions constructed of metal or containing metalcomponents. We recommend that you install the Access Points on the corridorceilings. The radio waves propagated by the BreezeNET PRO.11 LAN are reflectedalong the metal partitions and enter the offices through the doors or glass sections.

Basic Installation


2.4 Connect the Unit to the Power SupplyThe unit operates on a power input of 5VDC, (1200mA , 1500mA peak) suppliedby the power transformer included with the unit.

Plug the output jack of the power transformer into the DC input socket on theunit. This socket may be located on the rear or side panel of the unit.

Connect the supplied power transformer to a power outlet - 110/ 220VAC.

2.5 Connect the Unit to the Ethernet Port Connect one end of a an Ethernet 10BaseT cable (not supplied) to the RJ-45

port on the rear panel of the unit (marked UTP).

Connect the other end of the connector cable to the Ethernet outlet:

When connecting an SA-10 or SA-40 to a PC, use a straight cable.

When connecting an AP-10 or WB-10 to a LAN, use a straight cable.

When connecting an AP-10 or WB-10 to a PC, use a crossed cable.

When connecting an AP-10 to a WB-10, use a crossed cable.

3.4.1 Station StatusStation Status is a read-only sub-menu that displays the current values of thefollowing parameters:

Unit's Mode Identifies the units function. For example, if the unit is anAccess Point, AP-10 appears in this field. If the unit is a Station Adapter i.e.,SA-10, SA-40 or a WB-10, SA-10, SA-40 or WB-10 appears in this field.

Unit's HW Address Displays the units unique MAC address.

Unit's WLAN Address (SA or WB) The address associated with the unit.For the SA-10, this is the address of the PC. For the SA-40 and WB-10, this isthe MAC address of the unit. This field does not appear when the unit is anAP.

Station Status (SA or WB) Current status of the station. This field does notappear when the unit is an AP. There are three options:

Scanning The station is searching for an AP with which to associate.

Sync Waiting for Address The station is synchronized with an APbut has not yet learned its WLAN MAC address (this option is relevantonly to the SA-10). The AP does not forward packets to the stationwhen it is in this mode.

Associated The station is associated with an AP and has adopted theattached PC MAC address (for SA-10) or uses the units H/W address(SA-40 and WB-10), and is receiving packets from the LAN.

AP Address (Station Only) For stations, this parameter indicates an addressof the AP with which the unit is currently associated.

Total Number of Associations since last reset (Station Only) For stations,this indicates the total number of associations and disassociations with variousAPs. This is usually an indication of roaming.

Current Number of Associations (AP Only) Total number of stationscurrently associated with an AP.



Maximum number of Associations since last reset (AP Only) Maximumnumber of stations that were associated with an AP since the last reset.

Current Number of Authentications (AP Only) Total number of stationscurrently authenticated with an AP. A station may be concurrentlyauthenticated with several APs, but is associated with only one AP at a time.

Maximum number of Authentications since last reset (AP Only) Maximum number of stations that were authenticated with an AP since the lastreset.

3.4.2 IP and SNMP ParametersAll BreezeNET PRO.11 units contain IP host software. This software can be usedfor testing the unit for SNMP management functions and for downloading softwareupgrades using the TFTP protocol.

IP Address IP address of the unit.

Subnet Mask Subnet mask of the unit.

Default Gateway Address Gateway address of the unit.

SNMP Traps Type 0 to disable SNMP trap sending. Type 1 to enable SNMP trap sending. When an event occurs, a trap is sent to

the defined host address (see the Appendix for a list of traps). You canconfigure the host address to which the traps are sent through SNMPmanagement.

Display Current Values Type A to displays information concerning thecurrent status of all IP-related items.

3.4.3 Wireless LAN (WLAN) ParametersThe WLAN Parameters menu contains the following options:

Hopping Sequence (AP Only) Hopping sequence of the unit. A hoppingsequence is a pre-defined series of channels (frequencies) that are used in aspecific, pseudo-random order as defined in the sequence. The unit hops from



frequency to frequency according to the selected sequence. When more thanone AP is co-located in the same area (even if they are not part of the samenetwork) it is recommended to assign a different hopping sequence to each AP.

Hopping sequences are grouped in three hopping sets (see the followingparameter). When setting up multiple APs in the same site, always choosehopping sequences from the same hopping set. This reduces the possibility ofcollisions on the WLAN.

This parameter is set only for the BreezeNET PRO.11 Access Point. It is notaccessible from any other BreezeNET PRO.11 unit. During the associationprocess, all other stations learn the hopping sequence from the Access Point.Different co-located WLAN segments should use different hopping sequences.

Hopping Set (AP Only) Hopping set (between 1 and 3) of the unit. Hoppingsequences are grouped in several hopping sets. Always use the same hoppingset per site.

The number of hopping sequences per set is different for each hopping standardaccording to the following table:

Table 3-1. Hopping Sequences

Hopping Standard Number of Sequencesper Hopping Set

Netherlands 5Europe ETSI 26France 11US FCC 26Japan 4Australia 20Israel 11Canada 10Europe ETSI (DE Model) 10Korea 4Spain 9



ESSID The ESSID (up to 32 printable ASCII characters) of the unit is a stringused to identify a WLAN. This ID prevents the unintentional merging of twoco-located WLANs. A station can only associate with an AP that has the sameESSID. Use different ESSIDs to segment the WLAN network and add security.

Note: The ESSID parameter is case-sensitive.

Maximum Data Rate Maximum data rate of the unit. BreezeNET PRO.11units operate at 1 Mbps, 2 Mbps or 3 Mbps. The unit adaptively selects thehighest possible rate for transmission. Under certain conditions (compatibilityreasons or for range/speed trade-off) you may decide to limit the use of higherrates.

Transmit Antenna Which antennas are used for transmission. Duringreception, a BreezeNET PRO.11 unit dynamically selects the antenna wherereception is optimal. In contrast, the unit selects the antenna from which it willtransmit before transmission. It usually uses the antenna last used for successfultransmission. In models with external antennas, sometimes only a singleantenna is used. In this case, Transmit Antenna should be configured totransmit only from that single antenna. Similarly, models using a booster or anLNA use only a single antenna for transmission. There are three possibilitiesfor configuration:

Use Two Antennas

Use Antenna No. 1 only

Use Antenna No. 2. only

Mobility BreezeNET PRO.11 stations optimize their roaming algorithmsaccording to the mobility mode parameter. For example, a stationary station ismore tolerant of bad propagation conditions. It assumes that this is a temporarysituation and is not caused by the station changing position. Initiating a roamingprocedure in such a case would be counter-productive.



In general, wireless stations can be used in one of three mobility modes:

High (Mobility) Type 2 for stations that may move at speeds of over30 km per hour.

Medium (Mobility) Type 1 for stations that may move at speeds ofover 10 km per hour, but not over 30 km per hour.

Low (Mobility) -Type 0 for stations that will not move at speeds ofover 10 km per hour. Stationary is the default value, and in almost allcases this is the best choice.

Load Sharing Type 1 to enable Load Sharing.

When installing a Wireless LAN network in a high-traffic environment, youcan increase the aggregate throughput by installing multiple APs to create co-located cells. Load Sharing allows the wireless stations to distribute themselvesevenly among the APs to best divide the load between the APs.

Note: When working in Load Sharing mode, both the APs and the units should beconfigured to Load Sharing Enabled.

Preferred AP MAC (Ethernet) address of the preferred AP You canconfigure a station to prefer a specific AP unit. When the station powers up, itwill associate with the preferred AP even if the signal from that AP is lowerthan the signal from other APs. The station will roam to another AP only if itstops receiving beacons from the preferred AP.

Display Current Values This read-only status screen displays currentWLAN parameters. Press any key to return to the WLAN Parameters menu.



3.4.4 BridgingThe Bridging menu contains the following options:

LAN to WLAN Bridging Mode (AP Only) The options are:

Reject Unknown Type 0 to allow transmission of packets only tostations that the AP knows to exist in the Wireless LAN (behind theWireless Bridge).

Forward Unknown Type 1 to allow transmission of all packets exceptthose sent to stations that the AP recognizes as being on its wired Ethernetside.

Intelligent Bridging Period Intelligent bridging enables smoothroaming of WB-10 units. When intelligent bridging is enabled, the APgoes into a special bridging mode for a fixed amount of time whenever awireless bridge (WB) roams into its area. This mode causes the AP toforward packets destined for the stations behind the WB-10 even thoughthey are known or were learned from the wired side (except that nolearning of the wired LAN will take place). Afterwards, the AP willswitch back to Reject Unknown bridging mode. This procedure preventspackets destined for stations behind the bridge from getting lost. Thevalue of this parameter is the length of time in seconds that the AP willremain in special mode.

Note: When connecting very large networks, it is recommended to set this parameterto Forward Unknown.

IP Filtering Whether IP filtering is enabled for the unit. Enable IP Filteringto filter out any other protocol (such as IPX) if you want that only IP trafficwill pass through the WLAN.

Tunneling Whether the unit performs tunneling. Enable Appletalk tunnelingif the network contains a mix of Ethertalk1 (ET1) and Ethertalk2 (ET2)stations to ensure smooth communications. Enable IPX tunneling if IPXprotocol is running over your network. Be sure to set all units to the sametunneling setting.



Broadcast Relaying (AP Only) Whether the unit performs broadcastrelaying. When Broadcast Relaying is enabled, Broadcast packets originatingin WLAN devices are transmitted by the AP back to the WLAN devices, aswell as to the LAN. If it is disabled, these packets are sent only to the localwired LAN and are not sent back to the WLAN. Disable Broadcast Relayingonly if you know that all Broadcast messages from the WLAN will be destinedto the wired LAN.

Unicast Relaying Whether the unit performs Unicast relaying. WhenUnicast Relaying is enabled, Unicast packets originating in WLAN devicescan be transmitted back to the WLAN devices. If this parameter is disabled,these packets are not sent to the WLAN even if they are intended for deviceson the WLAN. Disable Unicast Relaying only if you know that all Unicastmessages from the WLAN will be destined to the local wired LAN.

3.4.5 Station ControlThe Station Control menu contains the following options:

Reset Unit Type 1 to reset the BreezeNET PRO.11 unit and apply anychanges made to the system parameters.

Load Defaults When this option is implemented, system parameters revertback to the original factory default settings. There are two options:

Load Full Factory Defaults All parameters revert to defaults exceptfor Japan Call Sign (if applicable) and Hopping Standard.

Load Partial All parameters revert to defaults, except for Japan CallSign (if applicable), IP Address, Subnet Mask, Default Gateway, HoppingSequence, Hopping Set, ESSID, Transmit Diversity, Long Range,Preferred AP, IP Filtering, Hopping Standard, Power Level, AutoCalibration, Encapsulation, WEP Attributes, Authentication Algorithm,Pre-authentication, WEP Default Keys, Ethernet Disable, Trap HostAddresses.



3.4.6 Security (Authentication Feature)Wired Equivalent Privacy (WEP) is an authentication algorithm which protectsauthorized Wireless LAN users against eavesdropping. The definition of WEP isdefined in the 802.11 standard. Refer to Section 9.5.2 in the Appendix of this guidefor further information.

WEP, also referred to as the Privacy option, must be ordered specifically and is notsupported by default. The security mechanism involves configuration of thefollowing parameters:

Authentication Algorithm This module operates in two modes:0-Open System (default): no authentication.or 1-Shared Key authentication (for systems that have the privacy optionimplemented).

Default Key ID The key to be used for the encryption of transmittedmessages.

Pre-authentication Set this parameter to Enabled when there is a great dealof roaming between the APs. Pre-authentication must be activated on both theAPs and the stations.

Privacy Option Implemented Yes if Shared Key authentication issupported, No if Shared Key authentication is not supported.

WEP Key# 1-4 The four encryption keys must be set before you can use theShared Key Authentication mode. The encryption keys you enter for the AP,must match those defined in the stations. Each key is a combination of 10 Hexdigits.

Note: It is recommended to change the encryption keys periodically, to enhancesystem security.

3.5.1 Translation Mode

The translation mode determines how the unit handles 802.3 packets. Thetranslation mode is either enabled (default) or disabled.



3.5.2 Performance

The Performance menu determines the unit performance:

Dwell Time (AP Only) The time spent on a radio channel before hopping tothe next channel in the sequence.

RTS Threshold Minimum packet size to require an RTS. For packets with asize below RTS Threshold value, an RTS is not sent and the packet istransmitted directly to the WLAN.

Max Multicast Rate Multicast and Broadcast transmissions are notacknowledged, therefore the chance of error increases. By default, the unit willalways transmit broadcasts, multicasts and control frames in the minimumpossible rate, 1Mbps.

Power Save Support If you enable Power Save Support on one of theWLAN stations (SA-PCR only), you must also configure the AP unit. PowerSave Support is influenced by two parameters:

DTIM interval on the AP side Determines at which interval the APwill send its broadcast traffic (default 4 beacons).

Listen interval on the SA-PCR side Determines when the station willwake up to listen to unicast packets which are destined to it (defaultvalue: 4 beacons).

DTIM Period Determines at which interval the AP will send its broadcasttraffic to all the stations in the cell, both stations that are in power save modeand to stations that are not in power save mode (normal mode). When stationsthat are in power save mode wake up to receive broadcast frames, they canalso poll the AP for the unicast frames if there are any stored in the APsbuffer. Default value is 4 beacons (approximately every 1 second).

IP Stack By default this parameter is disabled, to check connectivity. Anychanges to this parameter will be returned to the default value whenever theunit resets.

Acknowledge Delay Enlarges the range of system but can only be enabledfor links above 20kms. It must be enabled on both sides. The values are Longor Regular (default) and can be configured by an Installer or Technician.



P.S. Broadcast Reservation Percentage Determines the buffer spacereserved for broadcast frames in percentages. Default value is 30% ( Autostoring - no reservation). Allowed range is 0%-30%.

Note: It is recommended to leave it at default setting.

3.5.3 Radio

The Radio menu contains the following parameters:

Hopping Standard The Hopping Standard is a set of rules regarding theradio transmission standard allowed in each country. Units will work togetheronly if set to the same hopping standard. Use this parameter to set the unitshopping standard to that of the relevant country.

Power level Output power level at which the unit is transmitting. There aretwo possibilities, Low (4dBm) or High (17 dBm) at the antenna connector.

3.5.4 Rate

Multi-Rate Support When this parameter is enabled, the unit willautomatically switch to the best transmission rate at any given time. When theparameter is disabled, the unit will always stay at the maximum rateconfigured in the WLAN Parameters menu.

3.5.5 AP Redundancy SupportWhen the AP identifies that the Ethernet link has been discontinued over a definedperiod of time, it then stops transmitting and forces the stations associated with it toassociate with another AP.

The default mode for the AP Redundancy Support parameter is disabled (the APcontinues transmitting even when the ETH link is discontinued). This can only beconfigured by a Technician. It is recommended to use this parameter only whenmore than one AP is connected to the same distribution system and this AP isconfigured to the same ESSID.



3.5.6 Maintenance

The Installer has access to modify the following parameter of the Maintenance menu:

Auto Calibration When the unit is started, it performs an internal self-test.A part of this test is automatic calibration of the DC Offset and deviationpattern. Auto Calibration is not supported in the DE models, and therefore,must be disabled for DE units.

Japan Call Sign The Japan Call Sign is part of the Japanese standard,defined according to local regulations. The Japanese Ministry ofCommunications supplies an activation code for the units; this code is set inthe factory for each unit.

3.6.1 System CountersThe System counters are a simple yet efficient tool for monitoring, interpreting andanalyzing the Wireless LAN performance. The counters contain statisticsconcerning Wireless and Ethernet frames. The sub-menu contains the followingoptions:

Display Ethernet and WLAN Counters Choose this option to display thecurrent value of the Ethernet and Wireless counters. Refer to Sections 3.6.1.1and 3.6.1.2 for a detailed description of the counters.

Display Rate Counters Displays contents of packets at each rate. The APdisplays counters per station.

Display Rx Packets per Frequency Histogram of the number of framesreceived on each channel.

Reset Counters Choose this option to reset all counters. After choosing thisoption you will be requested to type 1 for confirmation or 0 to cancel the reset.

Power Saving Counters Displays the power saving counters per station, thenumber of transmitted frames and the number of discarded frames. Thisapplies only to APs.

3.6.1.1 Ethernet Counters

Ethernet counters display statistics about the units Ethernet port activity.

The unit receives Ethernet frames from its UTP port and forwards them to itsinternal bridge, which decides whether or not to transmit them to the WirelessLAN. The units have a smart hardware filter mechanism which filters most of theframes on the LAN, and hardware filtered frames are not counted.

On the other side, frames which where received from the wireless LAN and someframes generated by the unit (answers to SNMP queries and pings which reached tothe unit via the UTP port), will be transmitted to the UTP port.



Available counters:

Total Received Frames Indicated the total number of frames that have beenreceived from the Ethernet port. This counter includes both bad and goodframes.

Received Bad Frames The number of frames with errors received from theUTP port. A large number of received bad frames indicates a problem in theUTP connection such as a bad UTP cable or hub port.

Received good frames The number of good frames (i.e. frames with noerrors) received from the UTP port.

Forwarded to the bridge The number of received frames that wereforwarded to the units internal bridge. This counter should be equal to thenumber of good frames unless the internal bridge is overloaded.

Missed Frames Frames that the unit recognized but failed to read due tointernal bridge overload. This counter should equal zero unless the internalbridge is overloaded.

Transmitted to Ethernet The number of frames transmitted by the unit tothe UTP port. i.e., frames that have been received from the Wireless side, andframes generated by the unit itself.

3.6.1.2 Wireless LAN Counters

Wireless counters display statistics about the units Wireless LAN activity.

Transmission to the wireless media includes data frames received from the UTPports, as well as self generated control and management frames. When a data frameis transmitted, the unit will wait for an acknowledge from the receiving side. If anacknowledge is not received, the unit will retransmit the frame until it gets
